4 Claims. (01. 12-33) This invention relates to pad boxes for use in by a direct mechanical connection between the applying pressure to shoes and is illustrated as mask plate and the bail which carries the toe embodied in a pad box for use in cement-attachplunger. I do not herein claim broadly the coning soles to shoes with the aid of a machine such nection of the mask plate with the plunger, this as that shown in United States Letters Patent being the invention of FrankR. Merritt and being 69 No. 1,897,105, granted February 14, 1933, on the claimed in his application Serial No. 683,930, filed application of Milton I-I. Ballard. August '7, 1933.

It justment of the toe plunger relatively to the shoe has a notch at its rear end shaped generally like will, of itself, carry the mask plate into proper the toe of a shoe. The mask plate is provided relation to the toe of the shoe. I efiect this with a pair of ears 56 each of which is connected with the bail 34 by a link 58 pivoted to the mask plate at one end and to the bail at the other. Thus the adjustment of the bail 34 and plunger 46 longitudinally of the pad box causes corresponding adjustment of the mask plate 52 in its slideway, and the horizontal distance between the mask plate and the plunger is maintained unchanged, so that the necessity for manual adjustment of the mask plate to accommodate shoes of varying lengths is avoided.

Having described my invention, what I claim as new and desire to secure by Letters Patent of the United States is:

1. A pad box comprising a frame, a flexible pad supported therein, a pressure transmitting bail longitudinally adjustable on the frame, a mask plate longitudinally slidably mounted in the frame above the pad, and a direct connection between the bail and the mask plate whereby longitudinal adjustment of the bail correspondingly adjusts the mask plate.

2. A pad box comprising a frame having a guideway extending longitudinally of the frame, a mask plate slidably mounted inthe guideway,

a pad supported in the frame below the mask plate, a pressure bail longitudinally adjustable on the frame, and a link connecting the bail and the mask plate whereby adjustment of the bail effects corresponding adjustment of the mask plate.

3. A pad box comprising a fluid-filled receptacle having a distortable shoe engaging wall, pressure sustaining means adjustable longitudinally of the receptacle, a mask plate overlying the distortable wall and mounted for longitudinal adjustment relatively thereto, means effective at all times to prevent movement of the mask plate away from said wall, and a connection between the mask plate and the pressure sustaining member whereby longitudinal adjustment of the pressure sustaining member correspondingly adjusts the mask plate.

4. A pad box for use in cement attaching soles to shoes comprising a receptacle having a distortable wall formed and arranged to receive a sole and shoe, a mask plate overlying the distortable wall adjacent to the toe of a shoe operatively positioned on the pad and mounted for longitudinal adjustment relatively thereto but restrained against movement therefrom, the inner edge of said mask plate being curved to conform approximately to the contour of the toe of a shoe, a pressure sustaining bail carried by the pad box and mounted for adjustment longitudinally thereof, and a link connecting the bail and the mask plate whereby adjustment of the bail longitudinally of the pad box effects a corresponding adjustment of the mask plate.
